To a/ZZ wiz/ont t may concern:

Be it known that l, WARD GRANT MER- RALL, a subject of the King of Great Britain, residing at Onondaga, in the county of Brant, Province of Ontario, Dominion of Canada, have invented certain new anduseful Improvements in Baling-Presses, of which the following is a specification.

My present invention pertains to'improvements in baling-presses ,the construction and advantages of which will be, hereinafter `set n forth.

The object of the invention is to provide a .i simple and efficient press, the mechanism being such 4that in one form the press may be readily transported and operated by an engine or the like, andin thesecond form it may be operated by horse-power, the essenj tialfeatures being employed in both constructions. Y

Referring to the drawings, Figure l is a vertical longitudinal sectional view. of the rear portion of the press, taken on' the line l 1 of Fig. 2; Fig. 2, a transverse vertical sectional view takenon the line 2 2 of Fig. l; Fig. 3, a longitudinal sectional viewshowing the press and a portion of a modified form of operative mechanismtherefor; Fig. 4, a side l elevationl of the remainder of the operative mechanism designed to work in conjunction with that shown in Fig. 3 Fig. 5, a top plan view ofthe actuating wheel or member and the connections shown in Fig. A; Fig. `-6, a horizontal sectional view taken onthe line 6 6 of Fig. 4, the parts being shown on a somewhat-enlarged scale; Fig. 7, a vertical sec# tionalview taken on the line 7 7` of Fi 6; Fig. 8, a perspective view of a portion o the operating -member or wheel as used in the modified construction; Fig. 9, a vertical` sectional view taken on the line 99 of Fig. 3

. Fig. 10, a similar view taken .on the line 10 10 of Fig. 3; Fig. l1, a like view taken on the line 11 l1 of Fig. 3 g Fig. 12, a horizontal sectional view taken on the line 12 l2 of and Fig. 13 a perspective view of the plunger and the attached parts.v i f The main body of the press is the same under both constructions, and certain other features are the same, the only difference bethe plunger is in one instance mounted directly-in the rear portion of thepress-body, while in the modification it islocated at a Fig. 10,r

(See Figs. 3 and l0.) The angledisposed T-shaped barsE, which are secured at their inner ends to the .side plates C, form a chamber for the reception of the compressed bale. A cross-bar F (see Fig. 9,) extends beneath the lowermost pair of angle-plates A, while a second cross bar or member G lies upon the upper face of the uppermost pair of angle-bars A. Tie-rods H pass through the outer ends of the lower bar F and through the outer ends of the upper bar G, the rods being deflected or provided with outwardly-curved sections I to permit them to pass the intermediate. bars or members lE. l The upper ends of the rods pass through a third crossbar J, the upper and lower ends of the rods being headed or provided with nuts to keep the bars F and J in position.

A toggle mechanism is interposed between the upper pair of bars-to wit, G and J and in the form shown comprises a shaft K, provided with right and left screw-threads that coact with threaded blocks L, which as they are moved in one or the other direction serve to shorten or lengthen the toggles formed by the members M and N, which, as noted upon reference to Fig. 9, are pivotally connected to the blocks andto the cross-bars Gand J. By actuating the toggles the angle-bars A may be brought closer together, and the height of the chamber into and through which the compressed bales are forced is somewhat restricted. The intermediatebars E are supportedat their outer ends by chains O, (see Figs. 3 and 9,) the chains preferably passing through the flanges of the bars E, (best indicated in Fig. 9,) though it is of course evident that they maybe attached to the bars in any desired manner. Saidbars are likewise prevented from being forced outwardly by the bale by the tie-rods H H, as will be seen upon reference to Fig. 9.. Itwill also be seen by reference to said iigurethat the inner faces of the T-shaped'bars E stand in alinement with the inner faces. ofthe anglefbars A, and consequently a passage is IOO ` formed through which thebale may be forced without tearing or breaking the outer layer thereof. The side walls of the box or compression-chamber are provided with a series of openings, thro'ugh which work spring-,actuated detents P, (see Figs. 3 and 12,) as is usual presses ,of this character.

Located at the forward end of the opening through which the hay or othermaterial to 4be baled is introduced provide a tucker, de

ysigned tovconiine the loose ends of the hayias the same is forced thereunder through the action' of the plunger. In theform shown the ftucker comprises a V-shaped member Q, (see Y 1 5 i Figs. 3 and10,)\which` extendsfrom sidei to 'silde' ioff the pressl andl projects downwardly 'finto' the ycompression-chamber- Said tucker *is providedwith outwardly-extending pintles,-which -are secured in 'bearings R, mountvgered-upon the angle-bars A. Arms S-eXtend outwardly from the opposite portion of the tucker, and springs T, connected `to y said arms 'and' to Ist-udsprojecting outwardly'from thepress-body, serve tohol'dfthe tucker in `zgthej'positionshown in Figr,l so that as-the ypress-plunger is movedv forward the tucker is `yraised-andv the springs are put under tension. `Uponareturnmovement of the plunger the tucker -will"be swung downward ory lintothe I 3o jposition shown Fig.. 3, thereby carrying the` loose ends ofthev lhayI or .other material being baled inwardly, 'forming a -neat end 'uponv the b ale.

'The-p-lunger U `(seefFigs. V3 -and13) `is of a -size to work-freely through thepress and is uprovided-at' its' lower side with a' pair. .of-'rollers V, which rest upon thelhorizontal mem *bers of thelowermost'- pairof-iangle-bars A, 4which; in effect, form atrackv for saidl rollers.

A4o nrorder toproperly positionand guide' the plungenl; provide four rods W, which extend lrearwardly therefrom and pass through or between -groovedguideero'llers X, v(see Figs. 1,13, and* 1 1,) ysaid-rollersserving to embrace fthefrods, and thereby prevent i thefplunger 'fronr tilting or tipping out ofl its proper posif' tion.

"To the upper rearside oftheplunger is se- .vcure'da guard or shield Y ofa width sufiicient 5er-to extend Vover-and, protect the parts which underlie it. Sai-d guard-or shield is sustained uponbothsides-bybrackets Z, (see-Figs. 3 ;.an*d11,) which are secured tothe uppermost :angle-members A inthe form'illustrated :teid @longitudinally :to permit `the passage therethrough of the'various actuating parts, i'hereinafterreferred to in detail.

ISecured tothe upper face of the-press are ooftwo uprights or standards a, in'which are vmounted bearinglbloeks' b, supporting a crossrshaft c. 'y Said shaftlhas secured to it a frame ."d,'-the.forw'ardi end of which'is pivotally. atstached to apacker'e, said packeribeing rela- 6 5 tively lheavy 'This packer is designed to -ally connected to the guide-rods W.

from side to side ofthe press.

v its limit of forward movement.

`force the hay or other material down into the opening formed in ,the upper portion of the press immediately in front of the plunger. To

maintain the packer in its upright position, thereis connected to it and to the standards a a wire or rod f, which, as will be seen upon reference to Fig. 3, maintains the vpacker in its vertical position at all times. To the rear end of the frame d is attached a link g, which in turn is pivotally connected to a cross-bar 7L, (see Fig. 11,) said bar in turn being pivot- From this it will be seen that astheplunger-is vmoved forward the rear end of the frame d will be depressed, and as a consequence the Ypacker will be elevated to the position shown 1 in dotted lines in' Figi 3.

ln other words,v as the plunger is moved"forwardly the packer is elevatedv preparatory tothe rearward movement of the plunger and the introduction of a fresh charge of material to be compressed.

The actuating mechanism for the plunger may be said toy comprise an actuating meinber or wheel carrying a series of studs or rollers v`which coact -with a toggle and serve, through the straightening of said toggle, to

-force the plunger forwardly each time one of said rollers comes into contact with' the togf gle--and Umoves out of alinement therewith.

In the form shown in F1 1 and 2 the actuat- 9 ing wheel or member is mounted 'directly in With the preferred construction, or that illustrated inFigs. 1 and 2, the actuating member takes the form of a large gear-wheel i, provided'with two studs y', carrying rollers 7:. Any number of A toggleysecured upon a fixed shaft o, which extends A roller y), Fi 1v and 2, is secured to the pin or bolt q, which connects the adjacent ends of the links Z and m.

With the parts inthepositions shown in Figs 1 and 2v and with the actuating member Ior gear i moving in the directioi'i indicated by the yarrowin Fig. 1roller7r willcome into -contact with the roller pandas a `conselquencewill force the link lm upwardly and tend to straighten the toggle, thereby forcing the plunger U forwardly into theV com- Ipression-chamber. The rollers will Aremain 3m contact until the toggle is substantially straight, at which time the plunger will be at A slight f urther rotation of the actuating meinberor gear t' will carry'the roller c out of contact with-the roller p, thereby pern'1i.ttingthe plungerl to be drawn backwardly by the togrglo-links l and m'which, by reason oftheir weight, A-will tend 4to assume 'the position shown in Fig. 1. The continued rotation ol'v the actuating member will of course bring the second stud and its roller into alinement IOC " endof the link J and prevent the roller Gr with the roller on the toggle, and the opera'- tion above setforth'will be repeated.

Motion is imparted to the actuating .mem-

. ber in any suitable manner-as, for'instance,

by a pinion r, a gear s, and a small. pinion t, the latter meshing lwith the. relatively large gear s and receiving its Ymotionthrough a shaft u, upon which mounted abandwheelv. e

` The construction be termeda "self-contained pressg.' but it may be desirable to` operate the .machine by horse-power, in which event an actuating member ofsubstantially the form `shown in Figs.` 6 and `8 would lbe employed and intermediate connections used between it and the plunger. Such a constructionis shown in detail in Figs. 3,' 4,5, 6., 7, 8, -and11. Under this construction the .actuating member w,

insteadV ofbeing driven through gearing, is provided witha series Iof yokes zr, mounted upon the outer portion. thereof,` fand a suitable socket-membery, secured orfformed at the inner ortion'thereof. -The actuating member ta es'substantially the l'form of a wheel, and beneath tlrecentrally-disposed socket member. y there isseeured `ahub 2.

. This hub surrounds orisv journaled upon a stud-axle A', which extends upwardly from a suitable base formed bya series of radiallydisposed armsB'.` vThe outer end of each of said arms is provided withy an upright or standard C, each standard havingv attached 'to it al pairof horizontally-disposed rollers D', which coact with aribor flange E', formed upon the periphery of the wheel or actuating member w. vAseries of rollers F is secured tothe under face of said factuating member w, said rollers standing in lalinementwith a roller G', (see Fig.. 6,)icarriedlby the connecting-.pinH' ofthe toggle-linkstIf J. .,The inner end of the toggle link or lever I is` ful- 1. crumed at K' to thebase, while the outerend lof the link or lever J' is connected toa rod.

L'. In order to properly position the outer from being deflected out of the path of travel of the rollers F', a pintle M is passed through the outerr end/of'said :link and through a grooved roller N', which works between guide-bars O and P',.which are secured to each other and to the'base. A- suitable brace Q' is connected to the outer end of the guidebar O', as willbe seen uponreference to Fig. 6.

A trough-shaped member R' is interposed between the brackets or legs S of the press and the base upon which the operative mech- -ried by the'legs S.

anism is mounted. The' rod L and a chain T', to which it is connected, lie within said trough-shaped member. The` chain passes about an idler U', secured upon a shaft car- (See Figs. 3 and 11.) The chain also passes over an idler V', a third idler W', and thence about the rounded end of a link X', to which it is secured, as shown thus far describedr may y designated by A2.

in Fig. 3. The link X', with the double link Y', which latter is pivoted at'Z', forms a toggle-joint for the'. actuationof the plunger, the

forward end -of the linkX being connected f lto the plunger of the press, as shown in Fig. 3.

yAs will be readily understood, rotation of the actuating member 'w in the direction indicated by the arrow in Fig. 6 will cause the toggle formed by the links I' and J `to be straightened and as a consequence will throw the rod L rearwardly and with Iit thechain T', which drawing upon the toggle formed by the links X' Y will straighten said toggle and forcethe plunger forwardly into the position shown in dotted lines in Fig. 3. As the roller F rides offv the roller G when-the toggle I' J is straightenedk the vplunger lwill be retracted, being drawn rearwardly through the weight of the toggle X: Y', which assumes the position shown in Fig. 3. As a consequence the chain T' will likewise be .drawn toward the -press land thetoggle I' J through itsconnection with'the rod L will be broken or brought into the ,position shown in Fig. 6.

It will of coursebe understood that the usual abutment-boards will' be employed in the formation of the bale. yboards is shown in section inFig. 3 and is The parts will be suitably'grooved to facilitate the passage of the binding-Wires about the compressed bale.

It is evident that the-bales as they are `completed`will be forced out by the next succeeding bale and that the degree of pressure at which the bales are to be formed may be regulated by .contracting the discharge end'or mouth ofthe press inthe manner hereinbefore set forth. l
